The team is working hard to provide a GA release of these cmdlets soon, but cannot share a committed date at this time

Please note that the Revoke-AzureADSignedInUserAllRefreshTokens and Revoke-AzureADUserAllRefreshTokens were renamed to Revoke-AzureADSignedInUserAllRefreshToken and Revoke-AzureADUserAllRefreshToken respectively to follow the Verb-SingularNoun naming convention.

Please note that there is a known issue in this release. If you get an error "The module 'AzureAD' cannot be installed or updated because the authenticode signature of the file 'AzureAD.psd1' is not valid." then please retry the install-module command with the SkipPublisherCheck Parameter.
